My Analog Discovery 2 is dead. I bought a new one, works fine. I think that mine was going dead slowly, the Win 10 update was just the final straw. Mine kept "disconnecting", at first it happened probably 6 months ago, it would disconnect often using 1 laptop (my newest one), so I used the AD2 on an old lab computer, then it started "disconnecting" on that one rarely at first, then quite often. It died on a recent Win 10 update, now it never "connects".
I never exceeded max conditions, I mostly used the logic analyzer on 3.3V circuits.
Do these things get repaired? Does Digilent do repairs?
